Outdoor optical cable, optical cable used outdoors. The opposite is indoor optical cables.
Outdoor fiber optic cable is a communication line that realizes optical signal transmission. The cable core is composed of a certain number of optical fibers in a certain manner, and is covered with a sheath, and some are also covered with an outer sheath.
Outdoor optical fiber cable is mainly composed of optical fiber (glass filament as thin as a hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value.
Outdoor fiber optic cable has a higher tensile strength, a thicker protective layer, and is usually armored (ie, metal sheathed). Outdoor optical cables are mainly suitable for interconnection between buildings and between remote networks.
Optical fiber jumper (also known as optical fiber connector) is used to make the jumper from the equipment to the optical fiber wiring link. The optical fiber jumper has a thicker protective layer, and is generally used for the connection between the optical transceiver and the terminal box. Commonly used fiber optic jumpers include: ST type, LC type, FC type, SC type.
Single-mode fiber jumper (Single-modeFiber): Generally single-mode fiber jumper is indicated by yellow, and the connector and protective cover are blue; the transmission distance is longer.
Multi-mode fiber jumper (Multi-modeFiber): Generally, multi-mode fiber jumpers are indicated in orange, and some are indicated in gray. The connectors and protective covers are in beige or black; the transmission distance is short.
fiber jumper connector explanation:
Sc: square fiber optic connector, FC: round with thread, ST: similar to BNC, LC: separate transceiver structure, MT-RJ: square, dual fiber at one end, integrated transceiver
Pc: direct contact, APC: 8 degree inclined contact surface, UPC: curved contact surface
Optical fiber coupler is also called optical fiber adapter. Fiber Adapter (FiberAdapter) is used to connect and couple optical fiber movable connectors. Choose the model according to the connector of the optical fiber connector. According to the structure of the connector, it can be divided into: FC, SC, ST, LC, MTRJ, MPO, MU, SMA, DDI, DIN4, D4, E2000, various forms, using good sintering technology to ensure excellent strength and stability (200~600gf Insertion force)
The scope of application of coupler:
·Optical fiber communication network·Optical broadband access network·Optical CATV·Optical instrumentation·Optical local area network
